I have 3bar but i think 4 bar would better suit my 0ver 30psi runs. Anyone... been searching and i cant find anything on 4 bar ones. GM universal is what i am looking for.

 

Vireen,
I don;t think any of us need the 4 bar yet..hehhe JK
did you try to contact geoff ? he was posting about 3 bar GM for cheap...

after you manage to max out a 3bar you can only tune off the 02 readout, i dont even think my DFI could be reprogrammed for a 4 if it exists. If you manage your 02 after 3 bar and continue to take out timing you should be okay. Are you planning on running the y2k turbo or thumper series????

 

thats what i been doing. The speed pro from what fuel air spark says it can run a 4bar sucessfully. so go figure. I am gonan run t 68-1 ball bearing series is what was reccommened for my rpm usage. If that dont work out i will go with the older t66 series .

 

damn Viren, I'm jealous....well anyways, try getting a hold of Team Bergenholtz, They utilize a 4bar map...SO does Steph and the AEM civic

 

I know Haltech sells a 5 bar sensor, but they seem to skip from 3bar to 5bar for some reason.

 

My friend was telling me lots of modded supras use 4bar mapsensors check http://www.supraforums.com He said they're pricy though.

 

time to call cali to find out whats the deal on these 4bar map sensors. Its cnat be that hard to find a gm 4bar map sensors. I know those v8 guys be pushing some massive boost through there SC kits.

 

from what I guess you need to flow 650CFM to run a 68-1 in the Comp map, sick numbers. I dont even know where to buy a boost gauge that will handle the numbers you are planning on. You must loose tons of resolution when you go to a 4 or 5 bar, fuel should be easy as you must make peak torque within the three bar and just back off a bit, then just pull a few degrees every PSI or so. good luck!
